l IMPROVMENT IN YDRANTS.

@le tlgthlile nient th in tlgrse tettcts ntcut mit mating rant rif-tigtsimio TO ALL WHOM IT MAY CONCERN:A

Be itlcnown that LH. J BAILY, of Pittsburg, in the county of Allegheny,andrStat'enf Pennsylvania, have invented a new and useful Improvement inHydrants; and I do hereby declare that the following is a full7 clear,and exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to theA accompanyingdrawings, forming part of this specification. y

This `invention relates to new and useful improvements -in l1y'drants, whieh improvements embrace the constrnetion and general arrangement ofparts, 'the provision made for preventing the oxidation of the outercasing, and for removing the working parts from the ease, for purposesof inspection or repairs. i

And the inventionconsists in forming the case of the' hydrant ofgalvanized iron, or protecting itfrom rust and eonsequentdecay bygalvanizing or coating the' samewith zine, and in the arrangement of theoperating parts of the hydrant, as will hereinafter be more fullydescribed.

Figure 1 represents x-vertical longitudinal seetionof the hydra-nt,/showing'thc parts of which VAit is cornposed, and the'manner of theirarrangement.y i

Figure 2 is a cross-section of g. 1, through the line a' x, showing thecraiik-shaft and its connection with the cam for operating thedischargevtube. i

Figure 3 isa horizontal view from the line yy.

Similar letters of reference indicate corresponding parts.

- A is the outer casing ofthe hydrant, which is atube formed ofiwroughtor cast met-al, and protected from rust .by galvanizing or coating itwithzinc inside and ont.

B is the base ofthe hydrant, to which is attached the supplypipe of thehydrant, forming a chamber for,

the valves and seats.

This section is formed of two pieces cryin two partsQseenred together,as seenl in the drawing, the partsl beingmarked e and d.

E is the discharge-tube.

Thistube extends into the part c of the section B.

F is a valve-seat,-which ismade to tthe enlarged part efe, as seen at g.

'7L is a valve on the lower end offthe tube E.

1 is a slotted adjusting-plate, with two inclined surfaces on the upperedge of its flange, as indicated in the drawing at J'. i 4

These inclined surfaces bear against the nnderlsides of the lugs 7c onthe case A, whereby the plate is crowded down against F, forcing ittightly into its place, g, when the tube'E is turned. i

There are holes in the plate I, marked l. I

m is a. nut on the tube E, with pins t', which enter the holes Z as therod is 4pressed-down, for makingthe proper adjustment or. fastening theseat F in'its place.

1t are slots in the plate, which allow it (when properly turned) to bedrawn up pastthe lugs r 7s, with the sea-t F and valve i,rwhen it isnecessaryto repair or inspect the same. l

For adjusting the seat F, and for removing the same with the tnbe andother parts, as mentioned, the cap of the hydrant o, the spout P, andthe cam-shaft R are removed.

The upper end of` the discharge-tube E iseonnected with the part markedS, in which the cam T works, and to which the spout P is attaehed.

v The cam is revolved in a slot or recess in S, and it will be seen inthe drawing .that as the shaft R has its bearings in the casing A, thethrow of the` cam will raise or lower the tube te open, or close thevalves.

u is a ball-valve, which has its seat in the lower part ofc, in the baseof the hydrant, as seen.

"The pressure of the water from the supply-pipe o keeps this'valveclosedin its seat, except when it is 4pressed down by the tube in operatingthe hydrant.

The valve-seat F being 'xed and properly'adjusted, the throw of the cam,when .the shaftis turned, will depress the tube and valves 7L and Au,which will allow water to poss into the space w, around the valve L, andthrough the apertures a: into the tube E.

A counter-movement ofthe com closes the valves.

'y is :t waste-holo in the tube E to prevent freezing.

It will thus be seen that by constructing n hydrant in the mannerdescribed, provision is'made for preserving the metal of vwhich it iscomposed, and for removing the entire operating parts from the easingwhenever desired, without the trouble and expense of digging up thehydrant lor disturbing its connection with the supply-pipe.

The action is sure; there being no springs employed, the movements areall positive.l

Having thus described my invention, I claim :1s new, and desire tosecure by Letters Patent- 1. The construction of the tube c, valve 7l.,removable seat F, and plate I, arranged to operate in connec-` tion withthe vulvel u, substantially es shown and described.

2. The hollow valve-tube E, the nutm,'tlie plate I, and the valve-seatF, constructed, arranged, and operating substantially as tnd for thepurposes described.
